WebbThe NMR spectrum of methyl isopropyl ether (CH 3 -CH (CH 3) 2) would be predicted to have three types of protons; the methyl group bonded to the oxygen, shifted to 4, a methyne proton (the CH), also shifted to the same region, and the isopropyl methyl protons, in a fairly 'simple' environment at 1. Webb24 apr. 2015 · Proton ( 1 H) nuclear magnetic resonance (NMR) spectroscopy. NMR gives us three different types of information: Chemical shift (δ) Peak integrals (literally integrals - area under the curve) Spin-spin coupling tells you what is near each other. NMR relies on nuclear spin states that have very small differences in energy.
